Problems solved by technology

It often happens that the VC playback image pauses when the EC writes normally. This is because the write operation returned by the IP SAN to the EC is fast enough, but the read operation returned by the IP SAN to the VC is too slow to catch up with the playback required by the VC. speed, causing the image to freeze

Embodiment Construction

[0064] As mentioned in the background technology, the division of resources in the existing video service storage and reading mechanism cannot be adjusted according to the specific performance requirements of the device, and cannot meet the specific service requirements in the read and write operations of each device, and thus may cause video service The loss of information affects the quality of video service processing, and further affects the user experience.

[0065] The technical solution of the present invention establishes a set of communication mechanism among video encoding equipment (EC), management equipment (Manager), storage equipment (IP SAN) and video client (VC), which is used to control the dynamic adjustment process of performance. Send performance adjustment requests or business normal notifications through ECs or VCs, transfer control messages to IP SANs from management devices, and run internal performance adjustment processes on IP SANs to balance the writ...

Abstract

The invention discloses a method, device and system for adjusting the reading and writing performance of video service information, which realizes the dynamic adjustment of the reading and writing performance of video service information, so that the reading and writing of each storage unit can be performed according to the reading and writing status of the video service information. The adjustment of the writing performance meets the reading and writing needs of the equipment, improves the processing quality of the system for reading and writing video business information, and improves the reliability of the video business.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for adjusting the reading and writing performance of video service information. Background technique [0002] Among existing technical solutions, a video surveillance technical solution based on an Internet Protocol (Internet Protocol, IP) storage area network (Storage Area Network, SAN) has been widely used. [0003] A video surveillance technical solution generally consists of a camera, a front-end video encoder (Encoder, EC), a monitoring management device, a back-end IP SAN, and a video management client (Video Management Client, VC). After the camera collects image data, the video codec performs digital encoding and compression processing on the analog video data, and then stores the video data in the storage device, and the VC client performs historical video playback. [0004] Such as figure 1 As shown, it is a control and data flow cha...
